Notes:
Thermal broadening of Cl+ electron stimulated desorption ion angular distribution (ESDIAD) patterns, related to the vibrational motion of the adsorbate, has been investigated by subtraction of patterns measured at different temperatures. In the case of Cl on Si(100), the observed difference pattern between 130 and 305 K indicates that azimuthally isotropic motion of Cl occurs about the most probable Si–Cl bond direction. Equal distributions from the in-plane and out-of-plane bending motions are observed, correlating with the ∼200 cm−1 frequencies associated with these motions.
